SPECIFICATION formingpart of Letters Patent No. 705,339, dated July 22, 1902. Application filed November 22, 1901.. Serial No. 83,336. (No model.)

To all whom, it may concern.-

Be it known that LFRANOIS ANTONIO (31-.

ORGIO, a citizen of the United States," and a resident of Baltimore, in the State of Mary-- land, have invented certain new and useful Improvements in Roller-Brackets for Window Shades and Curtains, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

The present invention relates to rollerbrackets for window shades and curtains, and has for its principal objects the production of brackets of the class mentioned which will be comparatively simple and inexpensive in construction and capable of being readily and securely applied to any point of the guidestrips of awindow frame without the employment of nails or other similar fastening devices and without'otherwise marring the parts of said frame. I

With the above purposes in View the invention consists, primarily,of aroller-bracket comprising a pair of clamp members or jaws designed to embrace and by means of an adjusting-screw securely clamp an inner guidestrip of the window-frame, the said clamp members or jaws each carrying a bearing for the reception of the journal of the shaderoller.

There are other novel features and details connected with the said invention which are fully disclosed hereinafter.

In the accompanying drawings, forming part of this specification, Figure 1 is an inside view of the upper portion of a window frame and sash, showing a pair of my improved brackets in position. Fig. 2 is a horizontal sectional view of the parts shown in Fig. 1, the "section being taken in the plane indicated by the broken line mm of said latter figure. Fig. 3 is a vertical face view of one of the brackets, the same being shown in a position at a right angle to that represented in Fig. 1. Fig. 4 is a detail face view of the bearing of the companion bracket. Fig. 5 is a plan view illustrating a modified form of roller-bracket.

A pair of the improved brackets are employed for each roller.

A B refer generally to therespective'brack- ;ets." As the construction of both brackets is of the guide-strip O at. the inner side of the window-frame. Those faces of the portions a a which bear against the .guide-strip'are provided with teeth or serrations a, so that they may bite and take a better hold on the same when clamped thereagainst. As the .portion (4 lies within the guideway of the sash D, it is necessarily made thin, so as not to interfere with the movements of the latter. The member A has also an integral car a projecting at a right angle to the portion a and in which is riveted the inner end of the. screw-rod A which extends'beyond the outer face of the guide-strip O. In threadedengage ment with the rod A is the head a of the pend jent bearing A the threaded engagement of the head permitting the bearing to be adjusted and positively held at any desired point along said screw by simply rotating the bearing to revolve its head before the application of the 'device to the guide-strip. By referring more particularly to Figs. 3 and 4, wherein the pendent bearings of both brackets are shown, it will be noted that both are similar except that the opening a of the bearing A has approximately parallel walls at two points to hold the key-ended roller-journal against turning and is intersected by an upper diagonal slot a constituting'an" entrance by which said journal may be moved into or out ofposition. The bearing B of the bracket B for obvious reasons has a simple circular bearing-opening b". The openings a b are located in boxes A and Bfl integrally suspended from their heads by short vertical necks 0 b respectively. The clamp member A also has an ear 0.", corresponding somewhat with the car a of the member A, the opening in the ear a", however, being such as to permit said member A to slide freely along the screw A which extends through its opening. The relatively angular portions a a of the memher A are such on their inner faces as to adapt them to conform to the configuration of that surface of the guide-strip which is presented toward the room. As such surface generally partakes of a convex or beading effect, the portions a a are correspondingly curved on their bearing-faces, the latter having vertical teeth or serrations (r to insure their taking hold of the strip-surface. In threaded engagement with the screw-rod beyond the ear a is the adjusting-nut Aflwhich is preferably circular and has a milled edge to facilitate its being turned.

From the foregoing description it will be seen that the clamp members of the respective brackets are adjusted and applied so that one of them embraces the inner corner portion of its particular guide strip, while the other member bears against the other (generally the curved or beaded) face of the strip. In this position they may be firmly secured by manipulatingthe adjusting-nut to cause them to clamp the strip 0 between them. Care should be exercised in having the bearingopenings of b of the respective brackets in horizontal alinement with each other to the end that the curtain or shade roller will be horizontally supported and the curtain or shade hang true. lhe in-and-out adjustment of the bearings A B can be effected to a nicety by simply turning each bearing on its screw prior to clamping its bracket in position. By reason of the fact that the ears a a are located outside of the angular members or jaws A A the specific engagement of the screw-rod, in connection with the other jaw-contracting means, results in said members or jaws being so moved that their serrated portions a a will be forced into engagement with the adjacent portion of the guide-strip, as well as effecting the engagement of the portions a a with the other faces of the same.

In Fig. 5 is represented a somewhat-modified construction. In this arrangement the major or body portion is presented by a horizontal yoke-shaped casting E, having the illner angular portion e, toothed or serrated on that face 6 designed to bear against the contiguous surface of the guide-strip, the angular portion e at the other end occupying a position in front of the beaded or curved surface of the strip and having a threaded perforation for the passage of a screw E, provided with an adjusting-head e facilitating the turning of said screw, the inner end of the latter turning in an opening therefor in a movable clamping jaw or member E the inner curved serrated face of which is adapted to conform to the adjacent surface of the guidestrip. The enlarged central portion of the casting E has a protuberance E in which is located the journal-opening, either plain orhaving an intersecting slot, according to requirements. As the several parts of the casting with the exception of the screw are in the form of small and simple castings, they may be readily produced and finished, and, if desired, afterward nickel-plated toimpartan attractive appearance thereto and render them a desirable adjunct as a window-fixture.

Considering their convenience and efficiency, these roller-brackets are decidedly i11- expensive.

I do not wish to limit myself to the constructions shown and described, as modifications and changes may be made therein without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a bracket for shade and curtain rollers, the combination with a jaw carrying a threaded horizontal rod of a second jaw sliding freely on said rod, an adjusting-nut outside of said second jaw and in threaded engagement with the rod for causing the jaws to clamp the guide-strip of a window-frame, and a journal-bearing having a portion in threaded engagement with the rod to horizontally adjust the bearing along the same.

2. In a bracket for shade and curtain rollers, the combination with a jaw carrying a threaded horizontal rod,of a second jaw sliding freely on the latter, an adjusting-nut outside of said second jaw and in .threaded engagement with the rod, for causing the jaws to clamp the guide-strip of a window-frame, a head in threaded engagement with the rod for adjustment along the same and suspending a bearing-box.

3. In a bracket for shade and curtain rollers, the combination with an angular jaw comprising portions a, a, toothed or serrated at their inner sides, an outer ear integrally projecting from the portion a, a threaded horizontal rod connected with said ear, a second jaw comprising portions a a correspondingly toothed or serrated, said second jaw having a similarly-projecting car through which the rod freely passes, and a nut for causing the portions a, a to clamp the guidestrip and inwardly move the portions to, a, to do likewise.

In testimony that I claim the foregoing as my invention I have signed myzname, in presence of two witnesses, this 9th day of November, 1901.
